These arrangements render absolutely impossible any creeping movement ofone of the rails relatively to the others. The Whole forms an absolutelyrigid and undistortable system which considerably reduces the effects ofthe flexure stresses and of the shocks which usually tend to dislocatethe apparatus. This results in a reduction of the wear of the runningsurfaces or treads and of the fish-plates, in a greater security againstthe risk of rupture of the elements, andin a longer life of thecrossing.

The point I and the wing rails 4 and 5'Which are the elements the mostliable to wear can be made of a metal harder than that of ordinaryrails. As these three rails have relatively small lengths, the increaseof price due to the use of a metal of better quality is not veryconsiderable, whilst the life of the crossing is rendered much'longer.

The central rail I of the apparatus which is the main characteristicelement of the present patent can be replaced by any member the shapeand construction of which are different fro-rn those illustrated, forinstance, by a forged or moulded member fulfilling the same function orimproving its qualities.

- Fig. 8 illustrates a modiiication in which the counter-point rails arebent in the vicinity of the end of the point or nose o-f the crossing inorder to immediately come in contact with the Wing rails. The mainobject of this arrangement is to prevent these latter rails fromsupporting any load.

The arrangements described above are of course given by way of exampleonly, all the details of construction, shapes, materials and dimensionsof this apparatus can be modified without departing thereby from thescope of the present invention.

I claim:

1. In a crossing, a rail section arranged in the axis of the crossing,planed portions in the head of the said rail section for forming thepoint of ther crossing, a first counterpoint rail parallel to the outerrails of the crossing extending Without interruption throughout thelength of the crossing and bent according to the angle thereof, a planedportion in the head of said rail parallel to the axis of the crossingand bearing throughout its length against the unplaned portion of thehead of the axial rail section, a second counterpoint rail symmetricalto the first counterpoint rail relatively to the axis of the crossing, afirst wing rail bent according to the angle of the crossing and arrangedexternally along the rst counterpoint rail, a second wing railsymmetrical tothe first rail relatively to the axis of the crossing, anopening in each of the counterpoint rails dispensing withrthe head onthe portion of the said rail extending between the portion bearingagainst the axial rail section and the portion bearing against thecorresponding Wing rail, and means for rendering rigid the said fourrails and the axial rail section.

2. In a crossing, a rail section arranged in the axis of the crossing,two planed portions in the head of the said rail section which areparallel to the outer rails of the crossing for forming the point, thesaid rail section extending beyond the point but only by its web and itsfiange, a rst counterpoint rail parallel to the outer rails of thecrossing extending without interruption throughout the length of thecrossing and bent according to the angle thereof, a planed portion inthe head of said rail parallel to the axis of the crossing and bearingthroughout its length against the unplane portion of the head of theaxial rail section, a second counterpoint rail symmetrical to the firstcounterpoint rail relatively to the axis of the crossing, a first wingrail bent according to the angle of the crossing and arranged externallyalong the first counterpoint rail, a second wing rail 4symmetrical tothe first rail relatively to the axis of the crossing, an opening ineach of the counterpoint rails dispensing with the head on the portionof the said rail extending between the portion bearing against the axialrail section and the portion bearing against the corresponding wingrail, and means for rendering rigid the said four rails and the axialrail section.
